Amtrak and the N.C. Department of Transportation have agreed to continue operating two trains in the state beyond Oct. 1.
A news release from the department said federal law enacted in 2008 required both parties to agree to new terms to continue operating the state-supported passenger rail service.
The Piedmont operates two daily round trips between Raleigh and Charlotte. The Carolinian operates one daily round trip between New York City and Charlotte. The state supports service between Charlotte and Washington.
For July, ridership on the Carolinian increased by 3.9 percent over July 2012, with revenue increasing by 7.9 percent. Ridership for the Piedmont increased by 2.4 percent, with revenue increasing by 7.3 percent.
The Piedmont has led all Amtrak routes in ridership growth over the past two fiscal years.
